SELF-PROPELLED POWER-MACHINE.

Specification of Letters Patent.

Patented Mar. 10, 122%.;

Application filed October 26, 1812. Serial No. 727.860.

To all whom it may concern:

Be it known that I, ARTHUR S. Cannons, av citizen of the United States, residing at Bartlett, in the county of Carroll, State of New Hampshire, have invented certain new and useful Improvements in Self-Propelled Po\vei'-r\lacliines; and I do hereby declare the following to be a full, clear, and dxact description of the invention. such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain novel and useful improvements in self propelled power machines. and while 1 have in the present instance shown my invention as embodied in an automobile, wood sawing apparatus, I wish it to be understood that it is not limited in its useful application to this particular purpose. For instance instead of employing the sawing mechanism in conjunction with my invention, I may substitute therefor any other suitable machine or apparatus which is desired and convenient to utilize, such for instance as a vacuum cleaner.

In carrying out my invention it is my purpose to provide a self-propelled apparatus, by means of which the mechanism to perform a specified work, may be transported from place to place, the engine or power employed for propelling being also utilized for driving the saw.

It is also my purpose to provide an apparatus which will embody in its structure the 'desired features of simplicity, convenience and elliciency.

\Vith the above recited objects and others of a similar nature in view, my invention consists in the construction, combination and arrangement of parts'set forth in and falling within the scope of the appended claim.

In the accompanying drawing like charactors of reference indicate like parts in all the views, and Figure 1 is a view in side elevation of a machine embodying my invention. Fig. 2 is a top plan view. Fig. 3 is a similar view with the engine and other parts mounted upon the body of the vehicle removed in order to clearly illustrate the drive mechanism. Fig. 4 is a longitudinal sectional view taken on the line 4-4 of Fig. 3. Fig. 5 is a similar view taken on the line 5--5 of Fig. Fig. 6 is a front view.

Referring now to the accompanying drawings in detail, the letter A designates the body of the transporting vehicle which also fulfils the purpose of a simnort for the sawing mechanism, this body including the'sidi'a pieces 1-1 and the end members 2--2 forznmg the rectangular frame it on which is mounted at the front thereo seat and tool box 3.

The numeral 4 designates an engine of a combined any approved type, preferably a h Ciro-can hon engine, upon. the pov've'r shaft 0 which I,

mount the fast and loose pulleys 5 and ii.

The front axle is shown at 7 carrying the traction wheels 8, while 9 designates the rear axle having the rear traction wheels 10, each of said rear traction wheels carrying concentrically therewith a circular rack 11.

The numeral 12 designates a counter shaftjournaled transversely in the frame of the vehicle and projecting at one end beyond the side of the vehicle frame, said projecting end having fast therewith the belt pullc 13' over which is adapted to run the ent less driving belt 14 driven from the fast pulley of the engine shaft. This counter shaft 12 also carries pulleys 15 and 16 fast therewith and in line with the belt pulleys 17 and 18., respectively, mounted upon the pinion cross shaft 19 located adjacent the rear end of the frame, this shaft carrying at its ends the pinion gears 20 meshing with the adjacent circular rack of the ground or traction wheels. An open belt 21 runs over the pulleys l5 and 17 whereby the shaft 19 may be driven in one direction to propel the vehicle one way, while a cross belt 22 runs over the pulleys 16 and 18 for driving the vehicle in the reverse direction. The open belt 21 is provided with a belt tightener pulley 23 op- I erated by the arm 24 and rod 25, the latter being shifted by means of the lever 26 pivoted to the bracket 27 at the front of the vehicle as at 28, said lever being under directeontrol of the operator on the seat.

Likewise, the cross belt 22 has a belt tightening pulley 29 operated by the arm 30 andthe rod 31. the latter being pivoted to the-lever which when the machine is stationary may be moved or shifted from the propellin counter shaft and ment with the puile 36 on the saw arbor.

The numeral 37 esignates a sliding sup- I port of any well known construction for the logs to be sawed, this sliding support being connected to the frame by suitable braces 38.

The numeral 39 designates a vertical steering rod carrying the steering hand wheel 40 at the upper end thereof, the lower end of the steering rod carrying the sprocket drum 41 around which pass the steering chains 42 connected to the front axles at 43 so that the machine may be steered in an obvious manner.

From the above description taken in con nection with the accompanying drawing, the construction and operation'of my apparatus will be readily apparent. When it is desired to Ipro e1 the vehicle in a certain direction, one o the belt pulleys is shifted to ti hten its drivin belt, and the power shaft 0 the engine is pfiiced in driving connection withthe counter shaft, the saw arbor being disconnected from the engine of course. The engine is now started and the vehicle proceeds to the ,predetermined lace. The propelling mechanism is now isconnected from the engine and the saw arbor or shaft placed in driving connection therewith when the sawing may proceed in the usual manner.

While I have herein shown and described' one particular embodiment of-my invention, I wish it to be understood that I do not conplaced in driving engagefine myself to all the-precise details of con struction herein set forth by way of illustration, as modification and variation may be made without departing from the spirit of the invention or exceeding the scope of the appended claim.

What I claim is:

A self propelled vehicle including a vehicle body, front ground wheels thereon, a rear axle equipped with traction wheels, gears carried by said traction wheels, a. shaft having gear connections with said gears, and having a pair of pulleys thereupon, a second shaft, driving means for'the second shaft, a cross belt and an open belt-- connection between both of said shafts, said belt connection being normally idle, Idlers Suspended from said body upon swinging brackets and engageable upon actuation of said brackets with respective belts whereby to tighten said belts independently of each other to impart advance or reverse rotation apalr of operating to said traction wheels, levers with racks therefor on said body, and link connections between said levers and said swinging brackets for moving said brackets to operative position upon actuation of said levers.

In testimony whereof, I aflix my signature, in presence of two witnesses.
